This program is a proof of concept that SOPA will not help prevent piracy. The program, implemented as a Firefox extension, simply contacts offshore domain name resolution services to obtain the IP address for any desired website

Part of SOPA is a provision that any tools for circumventing the DNS hijacking are themselves banned. So this extension would have to be removed from the Mozilla repository. At best, it would be distributed underground, and hence would not help to preserve the freedom of the average user.

SOPA specifically (without actually naming it) calls out addons.mozilla.org for the whole mafiaafire thing -- so under SOPA, this add-on wouldn't be allowed to stay up.

"[T]his version targets software developers and distributors as well. It allows the Attorney General (doing Hollywood or trademark holders' bidding) to go after more or less anyone who provides or offers a product or service that could be used to get around DNS blacklisting orders."

It would be quite ironic if the ultimate legacy of SOPA is to strengthen the web by evolving the nature of DNS.

I'm reminded of the past "victories" of the copyright lobby that ended up doing more harm (from their perspective) than good: shuttering Napster (which lead to the much better decentralized systems used for piracy today) and passing of the DMCA (which actually ended up giving legal coverage to businesses that profit from infringement).

Can someone find a link to the source code (it is licensed under the GPLv2)? I tried to open the xpi in a text editor, but no dice. I don't have much experience with FF addons, but I'd like to see exactly what's happening here.

An xpi is simply a zip archive, FYI.

xpi files are "normal" renamed zip files. Try extracting the contents using your favorite unzipping application. You should then get access to the source files.

I thought a major part of SOPA will be censoring sites, not just removing them from DNS. So even if you can resolve them offshore, they are going to be censored versions of the sites you know and love.

That would be awesome, eg P2P DNS, but I wouldn't want it to pass to see if that is the outcome.
